SinclairZXSpectrumConsole

The ZX Spectrum is an 8-bit personal home computer released in the United Kingdom in 1982 by Sinclair Research Ltd. Referred to during development as the ZX81 Colour and ZX82, the machine was launched as the ZX Spectrum by Sinclair to highlight the machine's colour display, compared with the black-and-white of its predecessor, the Sinclair ZX81. The Spectrum was released in eight different models, ranging from the entry level model with 16 KB RAM released in 1982 to the ZX Spectrum +3 with 128 KB RAM and built in floppy disk drive in 1987.

The Spectrum was among the first mainstream audience home computers in the UK, similar in significance to the Commodore C64 in the USA. The introduction of the ZX Spectrum led to a boom in companies producing software and hardware for the machine. The Spectrum is based on a Zilog Z80A CPU running at 3.5 MHz (or NEC D780C-1 clone). The original model Spectrum has 16 KB (16×1024 bytes) of ROM and either 16 KB or 48 KB of RAM. Hardware design was by Richard Altwasser of Sinclair Research, and the machine's outward appearance was designed by Sinclair's industrial designer Rick Dickinson.

Our Spectrum is part of a console manufactured by Griffin & George of London and was kindly donated by Andrew Borkett of the Faculty of Education in Cambridge University.
